Application filed January 25, 1907. Serial No. 353,987.

T c all whom it may concern.

Be it known that I, JOHN A. SMALLEY, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented. a certain new and useful Artificial-Stone Machine, of which the following is a specification.

The objects of my invention are to provide a machine of this class of simple, durable and inexpensive construction and in which the mold ends may be readily and quickly attached or detached and the mold sides readily and quickly adjusted toward or away from each other, so that the machine may be quickly and easily adapted for making stones of different sizes.

A. further object is to provide improved mold cores and partitions and improved means for detachably and adjustably supporting them in the mold.

A further object is to provide improved and simplified means for vertically adjusting the mold bottom and the cores thereon, whereby the operator may easily and quickly lower the said bottom containing said cores so as to remove them from the stone.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of the complete machine embodying my invention. At the upper right hand corner of the figure the mold side is removed to show the interior construction. Fig. 2 shows an enlarged detail perspective view of one of the bearings for supporting the mold sides and ends. Fig. 3 shows a top or plan view embodying my invention, the mold bottom at the right side of the figure being removed to show the core supporting plate and other parts. Fig. 4 shows a top or plan view of the mold with the cores arranged for making one complete stone. Fig. 5 shows a similar view with the cores and partition arranged to make two corner-stones. Fig. 6 shows a similar view with the cores and partition arranged to produce two corner-stones of different sizes from the stones that would be made by the arrangement shown in Fig. 5. Fig. 7 shows a plan view of the core supporting plate. Fig. 8 shows an enlarged detail sectional view of a part of a machine frame to illustrate the sliding bearing device for the mold sides, the mold side in said bearing device being shown in side elevation, and Fig. 9 shows a detail sectional view for illustrating the means for adjustably supporting the mold sides, the mold end in this figure being shown in elevation.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the main frame of the machine preferably made of structural metal secured to gether by bolts or rivets. WVithin each end portion of the frame are two upright guide rods 11 and at the central portion of the frame are two similar guide rods 12. These end guide rods are supported at their central portions by the brackets 13 secured to the frame and the upper ends of said guide rods are arranged on the same horizontal plane and are designed to support the off-bearing plate on which the artificial stone is formed.

The core sigpporting plate, as shown in Fig. 7, is indicate y the numeral 14 and is provided with lugs 15 at its ends having openings 16 to slidinglyreceive the rods 11 and openings 17 are formed in its central portion to slidingly receive the rods 12. Four transverse-slots 18 are provided in said plate to receive bolts for adjustably supporting mold cores, as will hereinafter appear, and on opposite sides of a transverse central line are four airs of bolt openings 19 to receive rack bars for raising and lowering said mold bearing plate. These rack bars are clearly shown in Fig. l and are indicated by the numeral 20. They project straight downwardly from the mold bearing plate. For operating these rack bars, I have provided at each end of the frame a transverse shaft 21 on which two segmental racks 22 are fixed, these segmental racks being arranged in mesh with the racks 20. On one of these shafts 21 is an arm 23 extended upwardly and on the other shaft 21 is an arm 24 extending downwardly. These arms are connected by a link 25 whereby the shafts are rocked in unison in opposite directions so that both end portions of the core bearing plate may be moved up and down in unison. On one of the shafts 21 is a lever 26 provided with a spring actuated pawl device 27 to engage a fixed sector 28 on the frame. In this way the core bearing plate may be raised or lowered by the operator and supported in any position of its adjustment.

At each corner of the top of the frame 10, I have formed a recess 29 to receive a bearing device for the mold sides and ends. Each bearing device comprises a body portion 30 having a longitudinal slot 31 therein de signed to receive a bolt 32 whereby the body portion may be adjusted transversely of the frame and fixed in any position of its adjustment. On the inner end of the body portion of the bearing device I have formed a bearing 32 extended transversely of the body portion and a bearing 33 extended longitudinally thereof. The mold sides are indicated by the numeral 34 and are provided on each end with a rounded journal 35 designed to enter the bearing 32 The mold ends are indicated by the numeral 36 and are provided with the rounded journals 37 designed to enter the bearings 33. ners of the mold sides and ends is a locking device 38 of ordinary construction, whereby the said parts may be firmly held together.

In Fig. 4 of the drawings, four straight cores 39 are shown. These cores are connected with the core bearing plate 14 by means of bolts 40 extended through the slots 18 and into the cores. Obviously cores of any size or shape may be substituted and any number of them may be placed on the core supporting plate. In Fig. 5, I have shown an arrangement of cores and partitions adapted for producing corner-stones. Two right-angled cores 40 are provided each having one end adjacent to one of the mold sides and each having its other end adjacent to the center of the mold. Two straight cores 41 are provided in line with the ends of the cores 40 and a straight core 42 is provided in the corner of the mold. A partition 43 is extended from one end of the mold longitudinally to a point between the corners of the cores 40 and then laterally to theadja! cent side of the mold. In this way a twopart corner-stone is formed which may be laid in the wall with as wide a space between the parts of the stone as may be desired, thus forming a wall with an air space in it. The partition 43 ispreferably supported in position by having its ends enter the notches 44 formed for them in the mold sides and ends.

In Fig. 6, I have illustrated a form of corner-stone similar to the corner-stone just described, except that the parts of the stone are of less thickness and, therefore, take less material, although the wall formed by these stones may be made just as thick as desired by spacing apart the parts of the stone to the desired degree. On the inner faces of the mold sides and ends, I have provided vertical ribs 45 which are provided for the purpose of forming vertical grooves in the stones which are desirable for receiving mortar or cement and thus binding the stones more firmly in the walls in which they are placed. I have provided an off-bearing At each of the cor plate 46 to rest on top of the guide rods 11 and 12 and having therein openings to receive the cores or partitions. Obviously a different off-bearing plate must be provided each time that the cores or partitions are rearranged or adjusted within the mold as the openings in said plate must conform to the arrangement of the cores and partitions.

In practical use my invention is especially designed for making stones of the kind to be formed into a double wall, that is, a wallwith an outer and inner layer of stone with an air space between them. I/Vhen it is desired to form stones for the body of a wall the cores are suitably arranged and a longitudinal partition placed in position as shown in Fig. 3. The core bearing late is adjusted to position directly unc er the offbearing plate and then the stonemaking material is placed in the mold in the ordinary way. Then the lever is operated to lower the core bearing plate and in this way the cores are removed from the stone. Then the hinged sides and ends of the mold are released and permitted to swing outwardly and then the off-bearing plate isgrasped and removed with the stone. If it is desired to make stones of different thickness, the'mold ends are removed and new ones of the desired size are substituted. This may be easily done by adjusting the bearings in which the said ends rest. This adjustment of the bearings does not affect the sup ort of the mold sides. When it is desire to form stones for the corners of adouble wall, it is necessary to have stones that are of L-sha e form. These may be easily and quickly formed by the use of my improved machine by adjusting the molds andpartitions as shown in Figs. 5 and 6-.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, therefor is-- 1. In an artificial stone machine, the combination of a frame having recesses formed 110 at the top of its corners, a bearin device slidingly mounted in each recess an formed with a longitudinal slot, a bolt for each bearing device extended through said slot and into the frame, each bearing device having a 115 bearing at one side and another at its inner end, mold sides having journals thereon mounted in the side bearings of the bearing devices, mold ends having journals thereon mounted in the end bearings of the bearing 120 devices, and means for locking the mold sides and ends together.
